Gxine open port
 

When I open Gxine for playing e.g. a video file on the internet, it plays it by opening up a specific TCP or UDP port for receiving the video data.
BUT how can open this port up manually without requesting a video file (so that it will play e.g. any video that is streamed to it from e.g. another PC on a LAN).

Any clues?

Many thanks
